Socket Joint Piece Makita 134877-2 1/2" Square Drive, Length 84 mm

Makita 134877-2 is a socket joint piece with a 1/2" square drive and an overall length of 84 mm. Designed to transmit torque at an angle, this universal joint enables access to fasteners located in confined, offset or obstructed areas. It connects to standard 1/2" sockets and torque tools to expand reach and maneuverability when a straight extension cannot engage the fastener directly.

Advantages

The joint's 1/2" square drive provides compatibility with a wide range of sockets and ratchets. Its compact 84 mm length balances reach and control, allowing access into tight spaces while maintaining tactile feedback. The universal joint construction permits angular movement to transfer torque even when the handle and fastener are not collinear, reducing the need for disassembly of surrounding components. Manufactured to match professional tool dimensions, it integrates with common workshops and service tool sets.

Suitable for

• Automotive repair where bolts and nuts are recessed or obstructed
• Construction and installation tasks in confined spaces
• General maintenance and service work requiring angled access
• Use with torque wrenches and ratchets that accept a 1/2" square drive

Key specifications

• Drive type: 1/2" square drive (male)
• Overall length: 84 mm
• Function: universal/socket joint for angular torque transmission
• Material: heat-treated steel construction for strength and durability
• Compatibility: fits standard 1/2" sockets and hand or powered torque tools

How to use

Select a compatible 1/2" socket and push it onto the socket joint's drive until it locks. Attach the joint to a ratchet, breaker bar, or torque wrench with a 1/2" input. Position the socket over the fastener; the joint allows the socket to approach at an angle when direct alignment is not possible. Apply torque gradually and maintain control to avoid abrupt impacts; when using a torque wrench, account for any angle-induced leverage differences and follow the torque tool manufacturer's guidance.

Usage recommendations

Inspect the joint and mating connections for wear or deformation before use. Use the joint within the rated torque range of the attached tools and sockets; avoid using the joint as a prying tool. Store in a dry place to reduce corrosion and periodically clean and lubricate pivot surfaces to maintain smooth angular movement.
